DETAILED DESCRIPTION

Example methods and systems are directed to manipulating a virtualobject based on thought. Examples merely typify possible variations.Unless explicitly stated otherwise, components and functions areoptional and may be combined or subdivided, and operations may vary insequence or be combined or subdivided. In the following description, forpurposes of explanation, numerous specific details are set forth toprovide a thorough understanding of example embodiments. It will beevident to one skilled in the art, however, that the present subjectmatter may be practiced without these specific details.

Augmented reality applications allow a user to experience information,such as in the form of a three-dimensional virtual object overlaid on apicture of a physical object captured by a camera of a device. Thephysical object may include a visual reference that the augmentedreality application can identify. A visualization of the additionalinformation, such as the three-dimensional virtual object overlaid orengaged with an image of the physical object is generated in a displayof the device. The three-dimensional virtual object may be selectedbased on the recognized visual reference. A rendering of thevisualization of the three-dimensional virtual object may be based on aposition of the display relative to the visual reference.

A system and method for generating and manipulating a virtual objectbased on thought is described. A reference identifier from a physicalobject is captured. Brain activity data of a user is received to obtaina brain activity data. The reference identifier and the brain activitydata are communicated via a network to a remote server. The remoteserver selects a virtual object based on the reference identifier andthe brain activity data. A communication from the server identifying thevirtual object is received. The virtual object is displayed in a virtuallandscape.

In an example embodiment, a device has an electric wave application, areference identifier module, and a virtual object generation module. Theelectric wave application identifies a state of mind of a user based anintensity and a pattern of an output of electric waves generated by theuser. The reference identifier module identifies a visual reference on aphysical object. The virtual object generation module identifies avirtual object based on the visual reference and the state of mind ofthe user, and generates, in a display, a visualization of the virtualobject engaged with an image of the physical object. The rendering ofthe visualization of the virtual object is based a position of thedisplay relative to the visual reference.

In another example embodiment, the device also includes an EEG brainwave sensor coupled to a head of the user to generate brain wave data, aheart rate sensor to generate heart rate data of the user, an eyetracking sensor to determine a gaze of the user on the display, alocation sensor to determine a geographic location of the device, and asocial network module configured to access social network informationassociated with the user. The electric wave application identifies thestate of mind of the user based on the brain wave data, heart rate data,the gaze of the user, the geographic location of the device, and socialnetwork information associated with the user.

In another example embodiment, the device also includes a visual gesturemodule that determines a focus area in the display and a feature of thevirtual object. The visual gesture module then changes a state of thefeature in response to the feature being in the focus area of thedisplay. As such, “visual gestures” in a device allow a user to selectand activate features in a display of the device without the user havingto use his hands to tap on a display of the device. For example, theuser makes a “visual gesture” by physically moving and reorienting thedevice, while the device's camera is displaying real-time imagescaptured from the rear-facing camera of the device. Since the device isoverlaying a depicted physical object with a generated virtual objectand its features, the physical motions and re-orientations of the deviceresults in a gesture that moves one of the features into the focus areaof the display and may result in an action being generated.

In another example embodiment, the visual gesture module determines afocus area in the display and a feature of the virtual object. Thevisual gesture module then changes a state of the feature in response tothe intensity of the output.

In another example embodiment, a storage device includes a database thatstores visual references, virtual objects associated with a combinationof a visual reference and corresponding intensity and patterns ofelectric waves from the user, and features of the virtual objects.Features of the virtual objects are configured to change state inresponse to the intensity of the output.

In another example embodiment, the focus area corresponds to apredefined portion of the display. The state of the feature changes inresponse to the feature being located within the predefined portion ofthe display.

In another example embodiment, the predefined portion of the displaycomprises at least one of an area central to the display, an areaadjacent to an edge of the display, an area adjacent to a corner of thedisplay, or a user-defined portion of a display area.

In another example embodiment, the state of the feature changes inresponse to the feature being located within the predefined portion ofthe display for a time duration exceeding a time threshold.

In another example embodiment, the state of the feature changes inresponse to the intensity of the output exceeding an intensity thresholdfor a time duration exceeding a time threshold.

In another example embodiment, the visual gesture module comprises afocus area detector and a feature state modifier. The focus areadetector detects a presence of the feature of the three-dimensionalvirtual object in the focus area of the display. The feature statemodifier changes a state of the feature in response to the feature beingpresent in the focus area.

In another example embodiment, the feature state modifier changes thestate of the feature by replacing a first component of the virtualobject in the focus area with a second component of the virtual objectin the focus area.

In another example embodiment, a non-transitory machine-readable storagedevice may store a set of instructions that, when executed by at leastone processor, causes the at least one processor to perform the methodoperations discussed within the present disclosure.

FIG. 1 is a block diagram illustrating a device 100 suitable forenabling selection of content based on visual gestures on the device andthought from a user of the device, according to some exampleembodiments. The device 100 may include sensors 102, a display 104, aprocessor 106, and a storage device 108. For example, the device 100 maybe a desktop computer, a vehicle computer, a tablet computer, anavigational device, a portable media device, a smart phone of a user,or a user wearable computing device (e.g., glasses). The user may be ahuman user (e.g., a human being), a machine user (e.g., a computerconfigured by a software program to interact with the device 100), orany suitable combination thereof (e.g., a human assisted by a machine ora machine supervised by a human).

The sensors 102 may include electrodes that measure electrical activityfrom a human. For example, the sensors 102 may include electrodes tomeasure EEG (electroencephalography) waves of brains, EMG(electromyography) waves of muscles, and EOG (electrooculogram) waves ofeyes. The sensors 102 can be used to monitor brainwaves through EEG bydetecting electrical signals about a person's level of concentration orstate of mind. The sensors may be implemented, for example, by using aheadset attached to a head of a user. In another example, the sensors102 can be used to monitor facial muscles to detect facial expressionsof the user.

In another example embodiment, the sensors 102 may also include: anoptical sensor (e.g., a charged-coupled device (CCD)), an orientationsensor (e.g., gyroscope), and/or an audio sensor (e.g., a microphone).For example, the device 100 may include a front-facing camera fortracking eyes movement and facial expression of the user, and arear-facing camera for capturing a picture or a video of a physicalobject (or another displayed virtual object). It is noted that thesensors 102 described herein are for illustration purposes and thesensors 102 are thus not limited to the one described. In anotherexample, sensors 102 may not be physically connected to the device 100but are instead coupled to the device 100 via wireless means such asWi-Fi and Bluetooth®.

The display 104 may include, for example, a touchscreen displayconfigured to receive a user input via a contact on the touchscreendisplay. In another example, the display 104 may include a screen ormonitor configured to display images generated by the processor 106. Inanother embodiment, the display 104 may be transparent or semi-opaque sothat the user can see through the display 104.

The processor 106 may include an electric wave (e.g., EEG brain waves)application 110 and an augmented reality application 112. The electricwave application 110 may determine a state of mind (e.g., relaxed,tense, happy, angry) of a user based on outputs from the sensors 102.The state of mind may be based on the intensity or pattern of theoutputs of the sensors 102. The augmented reality application 112 maygenerate a visualization of a virtual object (three-dimensional ortwo-dimensional) overlaid on an image of a physical object captured by acamera (not shown) of the device 100 in the display 104 of the device100. The virtual object may be selected based on a present state of mindof the user. The virtual object and features of the virtual object maybe further manipulated based on a change in the state of mind of theuser. In another embodiment, the virtual object may be furthermanipulated (e.g., by the user) by adjusting a position of the physicalobject relative to the camera lens of the device 100. Similarly, thevisualization of the virtual object may be manipulated (e.g., by theuser) by adjusting a position of the camera lens of the device 100relative to the physical object.

In one embodiment, the electric wave application 110 may identify theintensity or pattern of electric waves discharged from a human brainover a short period of time. Multiple electrodes may be placedthroughout the scalp of a user. Each electrode may be configured tomeasure different types of waves. For example, Delta waves are mostpresent during sleep. Theta waves are associated with sleep, deeprelaxation, and visualization. Alpha waves occur when relaxed and calm.Beta waves occur when actively thinking or problem-solving. Gamma wavesoccur when involved in higher mental activity and consolidation ofinformation. The electric wave application 110 may then identify a stateof mind of the user based on the outputs of the sensors 102. Forexample, the electric wave application 110 may use EEG electrodes aloneor in combination with other sensing devices (microphone, camera, andheart rate monitor).

In one embodiment, the augmented reality application 112 may identify avisual reference on the physical object and tracks the location of thevisual reference within the display 104 of the device 100. The visualreference may also be referred to as a marker and may consist of anidentifiable image, symbol, letter, number, machine-readable code. Forexample, the visual reference may include a bar code, a quick response(QR) code, or an image that has been previously associated with thevirtual object.

The augmented reality application 112 may generate and display avisualization of the virtual object engaged with an image or picture ofthe physical object in the display 104. The virtual object may begenerated based on the visual reference and the state of mind of theuser. Each virtual object may correspond to a unique visual referenceand corresponding state of mind (e.g., unique to that virtual objectwithin the augmented reality application 112). In another embodiment,the augmented reality application 112 renders the visualization of thevirtual object based a position and an orientation of the device 100relative to the visual reference in the physical object.

The augmented reality application 112 may determine a focus area in thedisplay 104. The focus area in the display 104 may correspond to apredefined area in the display 104. The predefined area may trigger anaction or a change of state in a feature of the virtual object in thedisplay 104. The feature of the virtual object may change state inresponse to the intensity of the outputs of the sensors 102 or inresponse to a present state of mind of the user (e.g., user is relaxed).The feature of the virtual object may also change in response to achange of the state of mind of the user (e.g., user is getting morefocused). The feature may also change state when the feature is presentin the focus area of the display (e.g., the engine of a displayedvirtual car is in the focus area). The focus area may be predefined bythe augmented reality application 112 or may be customized and definedby a user of the device 100.

The storage device 108 may be configured to store a database of visualreferences, virtual objects corresponding to the visual references,features of the virtual objects corresponding to the virtual objects,and corresponding states of mind. The features of the virtual objectscan change with the state of mind of the user. For example, the color ofthe virtual chair can change from blue to red as the user becomes morefocused. The virtual chair may be displayed in a blue color if the useris relaxed. In another example, features of the virtual object changewhen the features are present in the focus area of the display 104. Forexample, the visual reference may include a machine-readable code or apreviously identified image (e.g., a picture of shoe). The previouslyidentified image of the show may correspond to a three-dimensionalvirtual shoe that can be viewed from different angles by manipulatingthe position of the device 100 relative to the picture of the shoe.Features of the three-dimensional virtual shoe may include selectableicons on the three-dimensional virtual shoe. An icon may be selected oractivated by moving (e.g., repositioning, reorienting, or both) thedevice 100 to display the icon within a focus area of the display 104.For example, the focus area may be a central area of the display 104, acorner of the display 104, an edge of the display 104, or any suitablecombination thereof.

In one embodiment, the device 100 may communicate over a network (notshown) with a server (not shown) to retrieve a portion of the databaseof visual references, corresponding three-dimensional virtual objects,corresponding features of the three-dimensional virtual objects, andcorresponding states of mind. The network may be any network thatenables communication between or among machines, databases, and devices(e.g., the device 100). Accordingly, the network may be a wired network,a wireless network (e.g., a mobile or cellular network), or any suitablecombination thereof. The network may include one or more portions thatconstitute a private network, a public network (e.g., the Internet), orany suitable combination thereof.

Any one or more of the modules described herein may be implemented usinghardware (e.g., a processor of a machine) or a combination of hardwareand software. For example, any module described herein may configure aprocessor to perform the operations described herein for that module.Moreover, any two or more of these modules may be combined into a singlemodule, and the functions described herein for a single module may besubdivided among multiple modules. Furthermore, according to variousexample embodiments, modules described herein as being implementedwithin a single machine, database, or device may be distributed acrossmultiple machines, databases, or devices.

FIG. 2 is a block diagram illustrating modules (e.g., components) of theelectric wave application 110 in the device 100, according to someexample embodiments. The electric wave application 110 may include asensor module 202, an initialization module 208, an intensity module204, a pattern module 206, and a state of mind identification module210.

The sensor module 202 captures outputs from the sensors 102. Forexample, the sensor module 202 may capture electric waves generated by abrain of the user by using EEG electrodes positioned on the scalp of theuser. As previously described, the sensor module 202 may also captureoutputs from other types of sensors such as a heart rate monitor or afacial muscle monitor to further supplement outputs from the EEGelectrodes. In another embodiment, the sensors 102 may include a camerato detect the gaze of the user and determine where the user is look onthe display 104.

The initialization module 208 enables the electric wave application 110to initialize and calibrate outputs from sensors 102 based a particularuser. The user may be asked to relax while the initialization module 208captures a sample of outputs from the sensors while the user in arelaxed state of mind. The sample outputs may then be used as a baselineor a reference for the user.

The intensity module 204 measures the intensity of one or more sensors.For example, the intensity module 204 may measure the intensity ofelectrical signals of Alpha waves in combination with the heart rate ofa user to determine the user's relaxed state of mind. In anotherembodiment, the intensity may be based on a statistical computation(e.g., average or median) of one or more outputs from selected sensors.

The pattern module 206 measures a pattern of a combination of EEGelectrodes or sensors. For example, a user may generate a uniquebrainwave pattern when the user is thinking about a specific car. Thepattern module 206 may record the pattern of the outputs of the sensors102 and associate the unique pattern from the user with the specificcar. In another embodiment, the pattern module 206 identifies thepattern based on one or more outputs from selected or most relevantsensors. For example, the pattern module 206 may identify a uniquecombination of brain wave pattern when the user is looking at a car inthe display. The pattern module 206 determines that the user is lookingat the car using an optical sensor or a camera of the device 100.Outputs from electric waves associated with muscles of a user may alsobe used in combination with brain EEG to further increase theidentification of unique pattern (e.g., alpha brain wave pattern A,delta bran wave pattern B, facial muscle pattern C, and eyes looking atobject D in the display). As such, each unique pattern from the user maybe associated with a unique visualization of a virtual objectexperience. In other words, a unique pattern of sensors 102 triggers anidentification of a specific virtual object to be visualized in thedisplay 104. For example, pattern xyz with intensity x′y′z′ from sensors102 corresponds to an airplane. Pattern abc with intensity a′b′c′ fromsensors 102 corresponds to moving the airplane upwards.

The state of mind identification module 210 may thus determine andidentify a state of mind of the user based on the intensity module 204and the pattern module 206. For example, the state of mindidentification module 210 may determine that the user is happy, relaxed,angry, focused, hungry, or thirsty. In another embodiment, the state ofmind identification module 210 may determine a specific object (e.g., aminivan) or a specific action (e.g., open a door) that the user isthinking.

In another embodiment, the state of mind identification module 210determines a change in the state of mind of the user based on changesfrom the intensity module 204 and from pattern module 206. For example,the state of mind identification module 210 may determine that the userwho was previously relaxed is becoming tense.

FIG. 3 is a block diagram illustrating modules (e.g., components) of theaugmented reality application 112 in the device 100, according to someexample embodiments. The augmented reality application 112 may include areference identifier module 302, a state of mind module 312, a virtualobject generation module 304, and a visual gesture module 306.

The state of mind module 312 generates a state of mind of a user basedon the state of mind identification module 210 of the electric waveapplication 110. For example, the state of mind module 312 may indicatethat the user is relaxed or is thinking of a particular object oraction. The state of mind module 312 may also identify that a change inthe state of mind of the user based on the state of mind identificationmodule 210.

The reference identifier module 302 identifies a visual reference on aphysical object captured by sensors 102 of the device 100. For example,a camera of the device 100 captures an image of a physical object, suchas a page on a newspaper. The page on the newspaper may include anarticle and a picture. The picture may have been already identified as avisual reference in the storage device 108. The picture may beassociated with a corresponding three-dimensional model of an object(e.g., a virtual sofa).

The virtual object generation module 304 generates and displays avisualization of a three-dimensional virtual object engaged with animage of the physical object captured by the sensor 102 of the device100 (e.g., the virtual sofa floats and rotates on top of the magazinepage). The virtual object may be based on the visual reference (e.g., afurniture ad in the magazine page) and a state of mind of the user. Inone embodiment, each virtual object may be uniquely associated with avisual reference and a particular state of mind. The virtual objectgeneration module 304 renders the visualization of the virtual objectbased a position of the device 100 relative to the visual reference. Inanother embodiment, attributes of the virtual object may be based on thestate of mind of the user. For example, the virtual object generationmodule 304 may generate a blue color sofa when the state of mind of theuser indicates that the user is relaxed and is thinking of a sofa.Similarly, the virtual object generation module 304 may generate a redcolor sofa when the state of mind of the user indicates that the user isexcited and thinking of a sofa.

In yet another embodiment, the virtual object generation module 304generates a virtual object based on a change in the state of mind of theuser. For example, a blue color car may morph into a red color sofa whenthe state of mind of the user indicates that the user is getting moreexcited.

The visual gesture module 306 may determine a focus area in the display104 and a feature of the virtual object. For example, those features mayinclude points of interest or user-interactive objects on athree-dimensional virtual object. For example, the three-dimensionalvirtual object may include a three-dimensional floor plan with iconscorresponding to points of interest in the three-dimensional floor plan.An icon located in a room represented in the three-dimensional floorplan may be activated to generate more information (size of the room,description of the room, etc.) about the corresponding room. The iconmay be activated by the user tapping on the representation of the iconon the display 104.

In one embodiment, the visual gesture module 306 may change a state ofthe feature or activate the feature when the feature is in the focusarea of the display or based in response on the user state of mind. Forexample, the focus area may be set as a center area in the display 104.Using the previous example, the user may move the device 100 so that theicon of a room of interest may be displayed in the center area in thedisplay 104. The visual gesture module 306 may change the color or shapeof the icon to indicate the user that the icon has been selected. Inanother example, the room of interest may be highlighted in red based onthe user state of mind indicating that the user is excited.

Furthermore, if the user maintains the icon in the center area of thedisplay 104 for at least a predetermined amount of time (e.g., a fewseconds), the icon may change state or otherwise be activated toinitiate an action corresponding to taping on the icon. For example, adialog box may be generated in the display to provide a description ofthe room selected by the user.

In another embodiment, the visual gesture module 306 includes a focusarea detector 308 and a feature state modifier 310. The focus areadetector 308 detects a presence of the feature of the virtual object inthe focus area of the display 104. The focus area detector 308 may trackan eye movement of the user looking at the device 100 to determine aspecific area in the display where the user is looking at. For example,the focus area detector 308 may determine based on a motion, anorientation, and a position of the device 100 relative to the user andthe physical object that the user is looking at a particular area in thedisplay 104. The focus area detector 308 may also use one or more cameralenses in the device facing the user to extrapolate the position and amovement of the eyes of the user and thus the corresponding area on thedisplay 104 at which the user is looking.

The feature state modifier 310 may be configured to change a state ofthe feature when the feature is present in the focus area of the display104. For example, the feature state modifier 310 may activate a featurecorresponding to an area that the user is looking at using the eyetracking feature previously described. In another example, the focusarea detector 308 determines that the user is excited when looking at aparticular room in a floor plan displayed in the display 104. Thevirtual object generation module 304 may generate a virtualthree-dimensional model of the particular room with bright wall colors.

FIG. 4 is a block diagram illustrating modules (e.g., components) of afocus area detector 308 of the visual gesture module 306, according tosome example embodiments. The focus area detector 308 may include adevice relative position module 402, a center focus module 404, an edgefocus module 406, a timer module 408, an eye tracking module 410, and auser-defined area focus module 412.

The device relative position module 402 may be configured to detect theposition and the orientation of the device 100 relative to the visualreference on the physical object by using the sensor 102. For example, agyroscope may determine the orientation and position of the device 100.A camera can be used to determine the aim and angle of the device 100relative to the visual reference. In other words, the device relativeposition module 402 determines how far or how close the device 100 is tothe visual reference and how the device 100 is aimed at the visualreference.

In another embodiment, the device relative position module 402 detectsan orientation of the device. For example, the device relative positionmodule 402 may detect whether the device 100 is held in a landscape modeor portrait mode. The location of the focus area may depend on whetherthe device 100 is held in landscape mode or portrait mode. Further,features of the three-dimensional virtual object may be enabled ordisabled based on whether the device 100 is held in landscape mode orportrait mode.

The center focus module 404 may be configured to define the focus areaof the display 104 in the center of display 104. For example, the centerfocus module 304 may be configured to define an area in about the centerof the display 104 as the focus area. The area may be in the shape of acircle, oval, or any other shape. The area may be predefined by thevisual gesture module 306 or may be customized based on a userselection. For example, the user may be able to move the focus area toanother area in the display 104.

The edge focus module 406 may be configured to define the focus area ofthe display 104 at an edge of the display 104. For example, the edgefocus module 406 may be configured to define an area at an edge or in acorner of the display 104 as the focus area. The area may be in theshape of a circle, oval, or any other shape. The area may also bepredefined by the visual gesture module 306 or may be customized basedon a user selection. For example, the user may be able to move the focusarea to another area in the display 104.

The timer module 408 may be configured to measure the amount of time thedevice 100 has been pointed to the visual reference such that a featureof the virtual object is located within a focus area of the display 104.

The eye-tracking module 410 may be configured to track an eye movementof the user looking at the device 100 to determine an area in thedisplay of the device 100 where the user is looking.

The user-defined area focus module 412 may be configured to enable theuser to define and select any portion of area or any shape of area inthe display 104 to be used a focus area.

FIG. 5 is a block diagram illustrating modules (e.g., components) of thefeature state modifier 310 of the visual gesture module 306, accordingto some example embodiments. The feature state modifier 310 may beconfigured to change a state of a feature present in a focus area in thedisplay 104 as previously described. For example, if the focus area isin a center area of the display 104, the feature state modifier module310 may change the color of the icon to indicate the user that the iconhas been selected when the focus area detector 308 detects that the userhas maintained the icon in the center area of the display 104 for atleast a predetermined amount of time (e.g., a few seconds). In thatcase, the icon may change state or otherwise be activated to initiate anaction corresponding to taping on the icon. For example, a dialog boxmay be generated in the display to provide a description of the roomselected by the user.

In another example, the feature state modifier module 310 may change thecolor of the icon to indicate the user that the icon has been selectedwhen the focus area detector 308 detects that the user has maintainedthe icon in the center area of the display 104 for at least apredetermined amount of time (e.g., a few seconds) and when the state ofmind module 312 determines that the user has maintained a particularstate of mind for at least a predetermined amount of time (e.g., a fewseconds).

The feature state modifier 310 may include a state change visualizationmodule 502, and an action module 504. The state change visualizationmodule 502 may be configured to change an icon in the focus area. Forexample, the color or shape of the icon may change, or the icon may bereplaced with another icon or another user interface such as anotification box.

The action module 504 may be configured to trigger an action similar totapping on the icon on the display 104. For example, the action module504 may generate a message notification, a dialog box, a menu, or anyother action triggered by the presence of the feature in the focus areain the display 104 or by the state of mind of the user. In anotherembodiment, the action module 404 may be configured to generate acommunication from the device 100 to another device, for example, via awireless network.

FIG. 6A is a block diagram illustrating an example of a visualization ofa virtual object in the device based on thought, according to someexample embodiments. A user 601 is equipped with sensors 610, such aselectrodes that are positioned on the scalp of the user 601. Aspreviously described, sensors 610 may include other types of measuringdevices for measuring facial muscle activity and heart rate activityamong others. Sensors 610 may be physically coupled via wires to adevice 600 (e.g., mobile communication device). In another example,sensors 610 may communicate with the device 600 wirelessly usingwireless communication means (e.g., Bluetooth®, ZigBee®).

The user 601 points a rear camera 612 of the device 600 towards aphysical object 604 having a visual reference 606. As previouslydescribed, the visual reference 606 may include a picture, amachine-readable code, or any other identifier unique to the augmentedreality application 112 in the device 600. The physical object 604 maybe, for example, a page of a magazine or newspaper. In anotherembodiment, the physical object 604 and the visual reference 606 may becombined together (e.g., a poster or a cup). In such case, thethree-dimensional physical object may be used as a visual reference. Forexample, a three-dimensional object such as a cup having a specificpattern or design may be used as a visual reference. The device 600captures an image or a picture of the physical object 604 and the visualreference 606 using the rear camera 612.

The device 600 generates a visualization of a three-dimensional virtualobject in a display 602 of the device 600 based on outputs from sensors610 and the visual reference 606. For example, the device 600 maydetermine that the user 601 is geographically located at anarchitectural firm. The device 600 determines from the sensors 610 thatthe state of mind of the user 601 is focused on a high rise building. Inanother embodiment, a front facing camera 614 of the device 600 mayfurther enhance and provide additional data on the state of mind of theuser 601. For example, the device 600 may obtain a live picture of theuser 601 using the front facing camera 614 to determine a smile or afrown. In another example, the front facing camera 614 may be used forfacial recognition to determine the identity of the user 601. The device600 may retrieve preferences from the user 601 such as, for example,favorite colors or items. In another example, the device 600 determines,identifies, and manipulates a virtual object to be displayed in thedisplay 602 based on a combination of the geographic location of thedevice 600 (e.g., office, home, restaurant, city, country), time ofcapture (e.g., morning, afternoon, evening, holiday, weekend) of thevisual reference 606, orientation (e.g., portrait or landscape, howclose) of the device 600 relative to the visual reference 606,identification of the user 601 (e.g. using facial recognition, or logininformation), preferences of the user 601 (e.g., favorite color,favorite type of music) social network information (e.g, number offriends, interests, proximity of friends, postings) related to the user601, outputs from sensors 610 (e.g., EEG brain waves, EMG muscles waves,EOG eyes waves, heart rate, blood pressure), and the visual reference606.

The device 600 may then generate a visualization of a three-dimensionalvirtual object engaged with a picture of the physical object 604 basedon the state of mind of the user 601. In the present example, athree-dimensional model of a high-rise building 608 is rendered on topof an image of the physical object 604 in the display 602 for a focusedstate. In another example, if the user's state of mind is relaxed andthat the user is thinking about a beach house, the device 600 maygenerate a three-dimensional model of a beach house rendered on top ofan image of the physical object 604 in the display 602. As such, thedevice 600 determines a virtual object to be displayed in the display602 in response to the captured image of the visual reference 606 andthe present state of mind of the user 601.

FIG. 6B is a block diagram illustrating an example of a visualization ofan action on a virtual object in the device based on thought, accordingto some example embodiments. The device 600 determines a change in thestate of mind of the user 601 (e.g., the user is thinking about rain onthe building). The device 600 then generates a change in thevisualization of the three-dimensional virtual object in the display 602of the device 600 based on the change in the state of mind of the user601 in response to changes in outputs from sensors 610 and the frontfacing camera 614. For example, rain over the building 608 may bedynamically animated in the display 602 when the device 600 detects thatthe user 601 has focused on rain.

As such, changes of the already displayed three-dimensional virtualobject in the display 602 are determined based on the changes in thestate of mind of the user 601. In another example, the color of thebuilding 608 may change to a lighter hue when the user 601 becomes morerelaxed while looking at the building 608. In another example, thetexture of the building 608 may change to a rougher texture when theuser 601 becomes agitated.

FIG. 6C is a block diagram illustrating an example of a visualization ofan action on a virtual object in the device based on thought incombination with a visual gesture, according to some exampleembodiments.

The front-facing camera 614 of the device 600 may capture and monitor agaze of the user 601. In other words, the device 600 may be capable oftracking eye movement to determine where on the display 602, the user islooking at. In another embodiment, the front-facing camera 614 of thedevice 600 determines the gaze of the user 601 using a combination ofeye-tracking movement and head-tracking movement.

The building 608 may include points of interest icons 618, 620, 622. Forexample, the point of interest icon 618 may provide additionalinformation corresponding to the location of the point of interest icon618 relative the three-dimensional model of the building 608, when thepoint of interest icon 618 is triggered or otherwise selected.

In one embodiment, a state of the point of interest icon 618 may bechanged to in response to the user 601 viewing the point of interest 618and a state of mind of the user 601. For example, the point of interesticon 618 may change color based on the state of mind of the user 601.

In another embodiment, the device 600 may display more information aboutthe point of interest icon 618 in response to determining that the user601 is looking at the point of interest icon 618 and that the state ofmind of the user 601 corresponds to a focused state. For example, adescription box may pop up in the display 608 when the user 601 islooking at the point of interest icon 618 and the user 601 is determinedto be in a focused state using sensors 610.

In another embodiment, the user 601 has positioned the device 600relative to the physical object 604 such that the point of interest icon512 is displayed in a central area of the display 602 of the device 600.In one embodiment, a state of the point of interest icon 618 may bechanged to notify the user of the selection. For example, the color ofthe point of interest icon 618 may be changed to bring attention to auser of the device 600.

In another embodiment, the front-facing camera 614 tracks an eyemovement of the user 601 viewing the building 608 in the display 602 ofthe device 600. The device 600 determines that the user 604 is lookingat an area (e.g., flag pole) on the display 602. The area may correspondto a pre-identified location on the building 608. The pre-identifiedlocation may include a point of interest on the building 608 associatedwith area. For example, the device 600 detects that the user 601 islooking at the flagpole of the building 608 for a few seconds. In oneexample, a dialog box showing more information about the flag pole maybe displayed. In another example, the device 600 may generate any otheraction associated with the pre-identified location on the building 608.

In another embodiment, the device 600 may include a transparent display(not shown) that may be used to identify a physical object or aparticular location on the physical object. In one example, thetransparent display may be mounted to a head of the user (e.g., viaeyeglass mount or headgear mount). In another example, the transparentdisplay may be a handheld device that the user 601 holds and looksthrough to see a physical object behind the transparent display. Therear facing camera of the device 600 may recognize physical objectsbeing looked by the user (e.g., by comparing an image of the physicalobject with a reference image). In particular, the position andorientation of the transparent display with respect to the user and thephysical object may be used to determine a line of sight of the user.Using the determined line of the sight of the user, the device canidentify in real time the physical objects being looked and inparticular which part of the physical object is being looked.

Once the device 600 identifies that the recognized physical object orthe part of the recognized physical object corresponds to apre-identified physical object or pre-identified part of the physicalobject, the device may trigger a corresponding action (e.g., sending anemail, generating a sound, etc.) based on the state of mind of the user601. For example, the device 600 detects the user 601 looking throughthe transparent display to a bottom portion of a television set. Thedevice 600 recognizes the television set and determines that the bottomportion of the television set (being looked at by the user 601) isassociated with an action corresponding to generating a communication tothe television set to switch the TV on or off. If the user 601 haslooked at the bottom portion of the television set for at least severalseconds and the state of mind indicates that the user is focused, thedevice 600 generates a corresponding signal to turn on or off thetelevision set.

In another example, the device 600 may display a virtual menu of TVchannels overlaid on the TV based on the state of mind of the user 601.For example, if the user is excited, the menu of TV channels may includesports channels and action movies. In another example, the user 601 maylook through a transparent display of the device 600 to a radio device.Similarly, a virtual menu of music channels may be displayed over theradio device based on the state of mind of the user 601. For example,the device 600 may display a virtual menu of classical or relaxing musicchannels when sensors 610 indicate that the user 601 is relaxed orsleepy.

FIG. 7 is a block diagram illustrating an example of a visual gesture totrigger a change in a state of a feature of the three-dimensionalvirtual object in the display of the device, according to some exampleembodiments. For example, when the device 600 detects that the point ofinterest icon 618 has been present in the focus area (e.g., center areaof the display 602) for at least a predetermined amount of time, anaction is triggered to change a state of the point of interest icon 618based on the state of mind of the user 601. For example, a dialog box702 may pop up, or another action (e.g., playing a media file, savingthe point of interest 618, emailing a description) corresponding to thepoint of interest icon 618 and the state of mind of the user 601 may bedisplayed on the device 600. In another example, the content of thedialog box 702 may be based on the state of mind of the user 601.

FIG. 8 is a block diagram illustrating an example of a visual gesture tofocus on a feature of the three-dimensional object in the device,according to some example embodiments. For example, the focus areas ofthe device 600 may be located in the corners 802, 804, 806, 808 of thedevice 600. Each corner may be associated with a corresponding action(e.g., triggering an action such as saving a point of interest) that isalso based on the state of mind of the user. For example, corner 802 maybe associated with sending an email. The recipient of the email may bedetermined based on the state of mind of the user. If the user is happy,the email includes a template compliment email to the head architect ofan architecture firm that designed the building 608. If the user isunhappy, the email may include a template complaint email to a customerservice department.

FIG. 9 is a block diagram illustrating an example of a visual gesture totrigger a change in a state of a feature of the three-dimensional objectin the device, according to some example embodiments. For example,because the point of interest icon 620 is within the focus area ofcorner 802 for at least a few seconds, the augmented reality application112 may generate a dialog box 902 to provide a description associatedwith the point of interest icon 510 and the present state of mind of theuser. As such, the user 601 of the device 601 is able to generateactions related to the three-dimensional object in the device withouthaving to tap on the screen or display of the device 601.

FIG. 10 is a flowchart illustrating an example operation of thevisualization application of a device in performing a method 1000 forvisualizing a virtual object based on thought, according to some exampleembodiments. In operation 1002, a state of mind of a user is identifiedbased on the intensity and a pattern of electric waves from a user. Inone embodiment, the operation 1002 may be performed using the electricwave application 110 of the device 100 of FIG. 1.

In operation 1004, an image of a physical object captured the device isrecognized or identified. In one embodiment, the operation 1004 may beperformed by the reference identifier module 302 that identifies avisual reference on the physical object.

In operation 1006, the virtual object generation module 304 identifies avirtual object based on the physical object (or a visual reference onthe physical object) and the intensity and pattern of the electric wavesof the user. In another example, other parameters may be used toidentify the virtual object. For example, heart rate data, voice datamay be used to identify the virtual object.

In operation 1008, the virtual object generation module 304 generatesand displays a visualization of a virtual object engaged (e.g., overlaidon top of) with an image of the physical object. The virtual objectcorresponds to the visual reference and the state of mind (e.g.,intensity and pattern) of the user. In one embodiment, the virtualobject generation module 304 renders the visualization of virtual objectbased a position of the display relative to the visual reference.

FIG. 11 is a flowchart illustrating an example operation of thevisualization application of a device in performing a method 1100 formanipulation of a virtual object based on thought, according to someexample embodiments.

In operation 1102, a change in the state of mind of a user is identifiedbased on a change in the intensity of outputs of sensors coupled to theuser. In one embodiment, the operation 1102 may be performed using theelectric wave application 110 of the device 100 of FIG. 1.

In operation 1104, the virtual object generation module 304 changes avisualization of the previously displayed virtual object in the displaybased on the change in the state of mind of the user (e.g., change inintensity and pattern of the output of the sensors). In other words, anaction may be performed on the virtual object in the display based onthe change in the change in the state of mind of the user. The virtualobject may be manipulated based on the change in outputs of the sensors.For example, the color of the virtual object may change from red to blueas the user becomes more relaxed. The virtual object may spin faster asthe user becomes more focused. The door of a virtual car may open as theuser becomes more focused on the location of the door on the display. Inanother example, the user initially thought of a lion. An image of alion is displayed. The user then thinks of a leopard. The image of thelion is then morphed into an image of a leopard on the device.

In one embodiment, the virtual object generation module 304 renders thevisualization of virtual object based a change in a position of thedisplay relative to the visual reference.

FIG. 12 is a flowchart illustrating an example operation of thevisualization application of a device in performing a method 1200 formanipulation of a virtual object based on thought and visual gestures,according to some example embodiments.

In operation 1202, a state of mind of a user is identified based on theintensity and pattern of outputs of sensors coupled to a human. Theoutput may include, for example, electrical brain waves. In oneembodiment, the operation 1002 may be performed using the electric waveapplication 110 of the device 100 of FIG. 1.

In operation 1206, the visual gesture module 306 determines a focus areain the display and a feature of the virtual object. The visual gesturemodule 306 changes a state of the feature in response to the featurebeing in the focus area of the display and in response to the state ofmind of the user (or a change of the state of mind).

In one embodiment, the reference identifier module 302 and the visualgesture module 306 store in a storage device of the device, a databaseof visual references, corresponding virtual objects, correspondingfeatures of the virtual objects, corresponding state of mind. Thefeatures of the virtual objects change state in response being in thefocus area of the display.

In one embodiment, the visual gesture module 306 changes the state ofthe feature in response to the feature being located within a predefinedportion of the display and the state of mind of the user. The focus areacorresponds to the predefined portion of the display.

In one embodiment, the predefined portion of the display comprises anarea central to the display, an area adjacent to an edge of the display,an area adjacent to a corner of the display, or a user-defined area.

In one embodiment, the visual gesture module 306 changes the state ofthe feature in response to the feature being located within thepredefined portion of the display for a time duration exceeding a timethreshold and a maintained state of mind exceeding a time threshold.

In one embodiment, the visual gesture module 306 detects a presence ofthe feature of the three-dimensional virtual object in the focus area ofthe display, and changes a state of the feature when the feature ispresent in the focus area (and based on the state of mind of the user).

In one embodiment, the visual gesture module 306 replaces a firstcomponent of the three-dimensional virtual object in the focus area witha second component of the three-dimensional virtual object in the focusarea. The feature may include an interactive object that changes statewhen the interactive object is in the focus area (and based on the stateof mind of the user). For example, interactive object may change colorwhen the interactive object is in the focus area.

FIG. 14 is a ladder diagram illustrating an example operation formanipulating a virtual object based brain activity data, according tosome example embodiments. A device 1402 (such as device 100) captures animage of a reference identifier from a physical object at operation1406. At operation 1408, the device 1402 also captures brain activitydata of a user of the device. At operation 1410, the device 1402communicates the reference identifier and brain activity data to aremove server 1404 via a network. The remote server 1404 retrievesvirtual object data associated with the reference identifier and brainactivity data at operation 1412. The remote server 1404 sends thevirtual object data to the device 1402 at operation 1414. The device1402 then displays the virtual image in a virtual landscape using thevirtual object data at 1416.

Modules, Components and Logic

Certain embodiments are described herein as including logic or a numberof components, modules, or mechanisms. Modules may constitute eithersoftware modules (e.g., code embodied on a machine-readable medium or ina transmission signal) or hardware modules. A hardware module is atangible unit capable of performing certain operations and may beconfigured or arranged in a certain manner. In example embodiments, oneor more computer systems (e.g., a standalone, client, or server computersystem) or one or more hardware modules of a computer system (e.g., aprocessor or a group of processors) may be configured by software (e.g.,an application or application portion) as a hardware module thatoperates to perform certain operations as described herein.

In various embodiments, a hardware module may be implementedmechanically or electronically. For example, a hardware module maycomprise dedicated circuitry or logic that is permanently configured(e.g., as a special-purpose processor, such as a field programmable gatearray (FPGA) or an application-specific integrated circuit (ASIC)) toperform certain operations. A hardware module may also compriseprogrammable logic or circuitry (e.g., as encompassed within ageneral-purpose processor or other programmable processor) that istemporarily configured by software to perform certain operations. Itwill be appreciated that the decision to implement a hardware modulemechanically, in dedicated and permanently configured circuitry, or intemporarily configured circuitry (e.g., configured by software) may bedriven by cost and time considerations.

Accordingly, the term “hardware module” should be understood toencompass a tangible entity, be that an entity that is physicallyconstructed, permanently configured (e.g., hardwired) or temporarilyconfigured (e.g., programmed) to operate in a certain manner and/or toperform certain operations described herein. Considering embodiments inwhich hardware modules are temporarily configured (e.g., programmed),each of the hardware modules need not be configured or instantiated atany one instance in time. For example, where the hardware modulescomprise a general-purpose processor configured using software, thegeneral-purpose processor may be configured as respective differenthardware modules at different times. Software may accordingly configurea processor, for example, to constitute a particular hardware module atone instance of time and to constitute a different hardware module at adifferent instance of time.

Hardware modules can provide information to, and receive informationfrom, other hardware modules. Accordingly, the described hardwaremodules may be regarded as being communicatively coupled. Where multipleof such hardware modules exist contemporaneously, communications may beachieved through signal transmission (e.g., over appropriate circuitsand buses) that connect the hardware modules. In embodiments in whichmultiple hardware modules are configured or instantiated at differenttimes, communications between such hardware modules may be achieved, forexample, through the storage and retrieval of information in memorystructures to which the multiple hardware modules have access. Forexample, one hardware module may perform an operation and store theoutput of that operation in a memory device to which it iscommunicatively coupled. A further hardware module may then, at a latertime, access the memory device to retrieve and process the storedoutput. Hardware modules may also initiate communications with input oroutput devices and can operate on a resource (e.g., a collection ofinformation).

The various operations of example methods described herein may beperformed, at least partially, by one or more processors that aretemporarily configured (e.g., by software) or permanently configured toperform the relevant operations. Whether temporarily or permanentlyconfigured, such processors may constitute processor-implemented modulesthat operate to perform one or more operations or functions. The modulesreferred to herein may, in some example embodiments, compriseprocessor-implemented modules.

Similarly, the methods described herein may be at least partiallyprocessor-implemented. For example, at least some of the operations of amethod may be performed by one or more processors orprocessor-implemented modules. The performance of certain of theoperations may be distributed among the one or more processors, not onlyresiding within a single machine, but deployed across a number ofmachines. In some example embodiments, the processor or processors maybe located in a single location (e.g., within a home environment, anoffice environment or as a server farm), while in other embodiments theprocessors may be distributed across a number of locations.

The one or more processors may also operate to support performance ofthe relevant operations in a “cloud computing” environment or as a“software as a service” (SaaS). For example, at least some of theoperations may be performed by a group of computers (as examples ofmachines including processors), these operations being accessible via anetwork and via one or more appropriate interfaces (e.g., APIs).

Electronic Apparatus and System

Example embodiments may be implemented in digital electronic circuitry,or in computer hardware, firmware, software, or in combinations of them.Example embodiments may be implemented using a computer program product,e.g., a computer program tangibly embodied in an information carrier,e.g., in a machine-readable medium for execution by, or to control theoperation of, data processing apparatus, e.g., a programmable processor,a computer, or multiple computers.

A computer program can be written in any form of programming language,including compiled or interpreted languages, and it can be deployed inany form, including as a stand-alone program or as a module, subroutine,or other unit suitable for use in a computing environment. A computerprogram can be deployed to be executed on one computer or on multiplecomputers at one site or distributed across multiple sites andinterconnected by a communication network.

In example embodiments, operations may be performed by one or moreprogrammable processors executing a computer program to performfunctions by operating on input data and generating output. Methodoperations can also be performed by, and apparatus of exampleembodiments may be implemented as, special purpose logic circuitry(e.g., a FPGA or an ASIC).

A computing system can include clients and servers. A client and serverare generally remote from each other and typically interact through acommunication network. The relationship of client and server arises byvirtue of computer programs running on the respective computers andhaving a client-server relationship to each other. In embodimentsdeploying a programmable computing system, it will be appreciated thatboth hardware and software architectures merit consideration.Specifically, it will be appreciated that the choice of whether toimplement certain functionality in permanently configured hardware(e.g., an ASIC), in temporarily configured hardware (e.g., a combinationof software and a programmable processor), or a combination ofpermanently and temporarily configured hardware may be a design choice.Below are set out hardware (e.g., machine) and software architecturesthat may be deployed, in various example embodiments.
